Lawn Care

What kind of weed am I dealing with?


Before I do anything crazy, can someone help me verify if this is wild Bermuda or crabgrass? I’m starting to get breakout patches in my Kentucky Bluegrass. Thank you.

  1. It’s worth mentioning, this is from different parts of my lawn, but it looks very similar

  2. Sidewyz1

    I’m no expert but that looks very similar to Saint Augustine.

    It’s grass, in Australia it’s called Buffalo and it’s pretty decent depending on the cultivar.

  4. TheWulfOfWullstreet

    Looks like clumping fescue or k31

  5. Beginning_Penalty804

    Looks like tropical signal grass or torpedo grass

    St Augustine grass. My entire yard is this.

    Why does reddit not have built in AI yet that automatically identifies all of the grass in every photo. Fuck you u/spez

    It’s not Bermuda or crab grass.

    Bermuda grows horizontally and has red tips while growing.
    Crab grass also grows horizontally.

    I thought this was a joke at first because my whole lawn is St Augustine grass

    Hard to tell for sure, there are parts of grasses you need to look at to fully identify one against the other in a photo and I can’t fully see in the pics. My best guess is quackgrass. Fescue was also a thought

    1000% saint augustine grass. It’s the main type of grass down here in FL. It will outcompete many different grasses/weeds.

    In the south, pretty sure that’s grass.

    As a Florida home owner, I can’t help but think of Anakin Skywalker when timing about St Augustine

    “I don’t like St Augustine grass. It’s coarse and rough and irritating, and it gets everywhere.

  14. Misanthropemoot

    Can confirm. My entire yard is like an airbed

    Lot of upvotes for St Augustine. At first glance, I can see why some of pics like. This is not St Aug.

    Couple of things. You have to zoom in and look at the characteristics. Saint Augustine spreads by stolons. Along the stolen, there are nodes. That is what the leaf blade grows from. They only come up from each node. The blades “Y” off from the node. It doesn’t telescope out from itself and the blades aren’t rolled at the bottom.

    In the bottom of pic 1 on the concrete, what looks like a purple stolon… you can telescoping with a rolled leaves at the bottom of blade. In the bottom of picture 3 , you can again see a telescoping stem with leaves coming off of that stem. I don’t see nodes. And, the tips of the blades are tightly rolled. The leaves are opposite of each other. On picture two, if you zoom in, you can see that the blades have very prominent parallel veins, and what looks to be a clasping auricale right in the middle.

    It can be very difficult to identify a weed without a seed head or a flower. There are many weeds that look very much alike, but the thing that distinctly sets them apart is the seed head. Without that we can only somewhat guess.

    For picture 2, it looks to be maybe clumping fescue or ryegrass. Picture 1 Could be a variety of crabgrass or maybe indica based on how it looks it’s spreading near the concrete. I tried looking at some extension offices websites for the north east. It’s possible that signal grass can grow in New York. The rest of the pictures possibly be signal grass, a variety of crabgrass mixed in OPs KBG. I see some that have prominent veins… could be something like mowed foxtail. I wouldn’t be surprised if wild Bermuda can be found in the north during summer. You can down vote me all you want, but this is 100% not Saint Augustine.

    100% not st. Augustine. It does however look similar to zoysia.

  17. Birdsandflan1492

    That’s not weed. That’s literally St. Augustine grass. Lol

  18. 2MuckingFuch

    I hate this shit. I have a fescue lawn and Bermuda grass and I are in a never ending battle.

  19. marxxximus

    It’s not a weed, obviously. Quit trolling my feed.

  20. Over_Marionberry9312

    Alexandergrass (Brachiaria plantaginea)

  21. Cum1retention

    Kinda looks like you may have both zoysia and St. Augustine? Might also be crabgrass/dallisgrass. Hard to tell tbh.

  22. Sea_Pickle6333

    Looks like the centipede grass that most yards in my neighborhood have. I absolutely detest it!
